Abstract
In order to implement the uniform load distribution of the gear train with dual power spliting, a pseudo-static model was built firstly. And then, according to the system power flow closed-loop feature, the torsional angle deformation compatibility conditions were deduced, the moment equilibrium conditions and elastic support conditions was established to calculate each gear pair transmission torque, and finally the system load sharing coefficient was obtained. Next, the relationship of the installation error and system load sharing characteristics was analyzed in the static research, and the floating pinion based on clearance floating played an important role in the system load sharing. The results show that the clearance of 0.8 mm could meet the pinion to floating under the influence of the gear 2 with installation error of 0.03 mm, obtain the load sharing coefficient of 1.0038, the floating pinion can improve the load sharing characteristics. Through theoretical data compared with the experimental data, in the same error conditions, power distribution is respectively 53.88% and 53.50%, which verifies the correctness of the method proposed.
